  U.S. Historical Research Returns as of December 2024

CRSP's Stock and Indexes Legacy Format (FIZ) files were discontinued after the December 2024 data release. Beginning with the January 2025 data release, we use the new Stock and Indexes Flat File Format 2.0 (CIZ) files to generate US research returns. Below is the historical data based on the Legacy (FIZ) format.

The momentum and short term reversal portfolios are reconstituted monthly and the other research portfolios are reconstituted annually. We reconstruct the full history of returns each month when we update the portfolios. (Historical returns can change, for example, if CRSP revises its database.) Although the portfolios include all NYSE, AMEX, and NASDAQ firms with the necessary data, the breakpoints use only NYSE firms. Missing data are indicated by -99.99 or -999.

In December 2012, we revised the market return used to measure Rm-Rf in the US. It is now the value-weight return of all CRSP firms incorporated in the US and listed on the NYSE, AMEX, or NASDAQ that have (i) a CRSP share code of 10 or 11 at the beginning of month t, (ii) good shares and price data at the beginning of t, and (iii) good return data for t. Previously we used the CRSP NYSE/AMEX/NASDAQ Value-Weighted Market Index as the proxy for the market return. The set of firms in the new series is more consistent with the universe used to compute the other US returns.

In January 2015, CRSP completed an extensive review of their shares outstanding data for 1925-1946. The file they released in January 2015 (with data through December 2014) incorporates over 4000 changes that affect 400 Permnos. As a result, many of the returns we report for 1925-1946 change in our January 2015 update and some of the changes are large. Please see Changes in CRSP Data for descriptions of data changes by CRSP affecting the data series above.

In May 2015, we made two changes in the way we compute daily portfolio returns so the process is closer to the way we compute monthly portfolio returns. In daily files produced in May 2015 or thereafter, stocks are dropped from a portfolio immediately after their CRSP delist date; in files produced before May 2015, those stocks are held until the portfolio is reconstituted, at the end of June. Also, in daily files produced before May 2015 we exclude a stock from portfolios during any period in which it is missing prices for more than 10 consecutive trading days; in daily files produced in May 2015 and thereafter, we exclude a stock if there is no price for more than 200 consecutive trading days.

Because of changes in the treatment of deferred taxes described in FASB 109, files produced from August 2016 on no longer add Deferred Taxes and Investment Tax Credit to BE for fiscal years ending in 1993 or later.

In August 2018, we have revised the method for computing Operating Profitability. We now include minority interest in the denominator, so the operating profitability ratio used to form portfolios in June of year t is annual revenues minus cost of goods sold, interest expense, and selling, general, and administrative expense divided by the sum of book equity and minority interest for the last fiscal year ending in t-1.

In September 2020, we removed the adjustment to book equity related to FASB Statement No. 106, Employers' Accounting for Postretirement Benefits Other Than Pensions, which was issued in 1990. This adjustment affects portfolios formed on book-to-market equity and portfolios formed on profitability, which is defined as operating income before depreciation and amortization minus interest expense scaled by book equity.

In September 2021, we transitioned from using our proprietary links between CRSP and Compustat data to those provided by CRSP after examining their consistency. We also updated the eligible universe through time to apply time-sensitive evaluation of stocks on criteria such as whether they are investment funds.

We now provide historical archives of the US monthly Fama/French 3 factors and 5 factors, as well as the 2x3 bivariate portfolio sorts used to construct the factors for each July data cut. The July cut has data through July and was released in August of that year.
